Belts
Some sweater dresses can look a little bulky and dumpy, camouflaging your curves and transforming you into a human sweater tent. Never fear — a simple nip at the waist can totally save your look. If your sweater dress hangs limp, wrap a belt or sash around your middle for an instant hourglass silhouette. For optimal curves, set your belt slightly above your belly button, at the smallest part of your waist. Play with color and texture, too. Try a patent leather or studded belt to offset the softness of your dress or add a splash of color to a neutral dress with a red or yellow belt.
Tights
Tights and sweater dresses go together like marshmallows and hot cocoa: They're both cozy, cold-weather pieces that become instant best friends when worn together. If you need a little extra windchill protection, opt for thicker leggings rather than tights. Either way, don't overlook these essential sweater dress companions. Go for neutral black or navy if your dress is patterned and vibrant or sport some bright-colored tights to spice up a plain sweater dress.
Shoes
If you're into clunky footwear, by all means, boot up. The thickness of a sweater dress means you can easily wear a bold pair of boots without throwing your look out of proportion. Knee-high leather boots, tights and a sweater dress is a pretty classic combination, though you can also try granny-style ankle booties. If you want more delicate footwear, slip your feet into a pair of wedges or basic ballet flats.
Accessories
Add a little bling to your look with some jeweled accessories. Think big, strong, vibrant pieces that can hold their own against the sweater dress — anything too small and delicate will look out of proportion. Try thick bangle bracelets, chandelier earrings or a chunky necklace. If jewelry's not your thing, accessorize with a scarf. Opt for a bright, cheery scarf if your dress is dark or plain; go with a neutral scarf with a bright, busy sweater dress.
